Blood glucose control and metabolic dysfunction-associated steatotic liver disease in people with type 1 diabetes.

PURPOSE: Metabolic dysfunction-associated steatotic liver disease (MASLD) may have distinctive pathophysiological features in type 1 diabetes (T1D). We evaluated the independent role of blood glucose control on MASLD in T1D. METHODS: In a cross-sectional study on 659 T1D adult patients, MASLD was assessed by the Fatty Liver Index (FLI) and the Hepatic Steatosis Index (HSI). Anthropometric, biochemical, and clinical parameters were retrieved from electronic records. Blood glucose control status was evaluated by dividing participants into subgroups according to the median value of HbA1c [7.6% (60 mmol/mol)], and this analysis was repeated excluding overweight/obese patients. RESULTS: Patients with HbA1c above 7.6% (60 mmol/mol) showed significantly higher MASLD indices (HSI 38 ± 6 vs. 36 ± 5, p < 0.001; FLI 26 ± 26 vs.19 ± 19, p < 0.001), and higher proportions of MASLD identified by HSI (57 vs. 44%, p < 0.001) and FLI (14 vs. 7%, p < 0.001) than patients with HbA1c below 7.6% (60 mmol/mol). Similar results were obtained for HSI after the exclusion of overweight/obese patients. Stepwise linear regression analysis confirmed that HbA1c was independently associated with HSI (r = 0.496, p = 0.009) and FLI (r = 0.722, p = 0.007); waist circumference with HSI (r = 0.492, p < 0.001); and waist circumference (r = 0.700, p < 0.001), HDL cholesterol (r = 0.719, p < 0.001), and LDL cholesterol (r = 0.712, p < 0.001) with FLI. CONCLUSIONS: Blood glucose control is a main factor associated with MASLD in adults with T1D, also independently of overweight and obesity. Appropriate therapeutic strategies focused on tight blood glucose control may also be needed for the prevention and treatment of MASLD in T1D.

Long term mortality and morbidity of Italian soldiers after deployment in Iraq as related to biomarkers assessment: Results of the SIGNUM study.

INTRODUCTION: The health profile of military veterans deployed in foreign operative theatres was assessed by several international studies because of potential exposure to depleted uranium and other pollutants. Here we reported results of 15-year epidemiological surveillance assessing long-term health effects in a cohort of Italian soldiers deployed in Iraq in 2004-2005 and participating in a biomonitoring campaign to identify potential genotoxic exposure to environmental xenobiotics before and after deployment (n = 981, SIGNUM cohort). METHODS: We evaluated mortality and hospitalization risks of the SIGNUM cohort retrospectively until 2016 and 2018 respectively. A wide cohort of military personnel never deployed abroad (n = 114,260) and the general Italian population were used as control populations in risk assessment. Causes of death and diagnoses of hospitalization were derived through deterministic record linkage with official national databases of mortality and hospital discharge. Standardized Mortality Ratio (SMR) and Standardized Hospitalization Ratio (SHR) were computed adjusting according to sex, age, area of birth, and calendar year. Differential pre-post deployment in xenobiotics concentrations and early effect biomarkers (oxidative DNA alterations and micronuclei) measured in blood serum were analysed in relation to cancer hospitalization. RESULTS: Mortality risk due to pathologies was more than halved compared to the general population (SMR = 0.41, 95% CI 0.11-1.05) and not significantly different compared to soldiers never deployed abroad (SMR = 0.69, 95% CI 0.19-1.68). Similarly overall hospitalization risk due to pathologies was decreased with respect to the general population (SHR = 0.86, 95% CI 0.80-0.92) and comparable to the control military group (SHR = 0.99, 95% CI: 0.93-1.06). For haematological cancers a decreased hospitalization risk compared to the Italian general population was observed (SHR = 0.38, 95% CI 0-0.92). No statistically significant differences emerged in the patterns of biomarkers in association with cancer hospitalization. CONCLUSION: The study confirms the so called 'healthy warrior' effect for the SIGNUM veterans and showed no correlation between cancer occurrence and biomonitoring markers measured on field.

Nailfold capillaroscopy in the rheumatological current clinical practice in Italy: results of a national survey.

This cross-sectional online study was designed by the study group on Capillaroscopy and Microcirculation in Rheumatic Diseases (CAP) of the Italian Society of Rheumatology (SIR) to provide an overview of the management of nailfold capillaroscopy in Italian rheumatology centers. Therefore, SIR distributed the survey to its members in July 2021, and each center's physician with the most expertise in capillaroscopy completed the questionnaire. The survey was completed by 102 centers, with at least one representative from each Italian region. Ninety-three centers perform capillaroscopy, and 52 (56) conduct more than 200 investigations annually. Seventy-eight (84%) of respondents have more than five years of experience with the technique, and 75 centers (80.6%) have received certification from specific national or international training courses. In 85 centers, a videocapillaroscope with 200x magnification is employed (91.4%). The average waiting period for the examination is 2.4 months, and less than 3 months in 64 of the locations (68.8%). The study demonstrates that capillaroscopy is an integral part of both the diagnostic phase of Raynaud's phenomenon and the monitoring of autoimmune connective tissue diseases (CTDs). However, the reporting methods and timing of patient followup are heterogeneous.

Sources and space-time distribution of the electromagnetic pulses in experiments on inertial confinement fusion and laser-plasma acceleration.

When high-energy and high-power lasers interact with matter, a significant part of the incoming laser energy is transformed into transient electromagnetic pulses (EMPs) in the range of radiofrequencies and microwaves. These fields can reach high intensities and can potentially represent a significative danger for the electronic devices placed near the interaction point. Thus, the comprehension of the origin of these electromagnetic fields and of their distribution is of primary importance for the safe operation of high-power and high-energy laser facilities, but also for the possible use of these high fields in several promising applications. A recognized main source of EMPs is the target positive charging caused by the fast-electron emission due to laser-plasma interactions. The fast charging induces high neutralization currents from the conductive walls of the vacuum chamber through the target holder. However, other mechanisms related to the laser-target interaction are also capable of generating intense electromagnetic fields. Several possible sources of EMPs are discussed here and compared for high-energy and high-intensity laser-matter interactions, typical for inertial confinement fusion and laser-plasma acceleration. The possible effects on the electromagnetic field distribution within the experimental chamber, due to particle beams and plasma emitted from the target, are also described. This article is part of a discussion meeting issue 'Prospects for high gain inertial fusion energy (part 2)'.

Ultrasound in the assessment of musculoskeletal involvement in systemic lupus erythematosus: state of the art and perspectives.

Musculoskeletal manifestations are extremely common in patients with systemic lupus erythematosus. Transient and migratory arthralgia is frequently reported even without clinical signs of joint or tendon inflammation. In less than 15% of patients, joints may be more severely affected by deforming (Jaccoud's arthropathy) and/or erosive arthropathy (Rhupus syndrome). In recent years, ultrasound has emerged as a promising imaging technique for the assessment of musculoskeletal involvement in systemic lupus erythematosus, having demonstrated the ability to detect inflammation and structural damage both at articular and periarticular level. Recent ultrasound studies have also revealed new insights into musculoskeletal involvement in patients with systemic lupus erythematosus, some of them questioning the traditional concepts of systemic lupus erythematosus arthropathy, with potential clinical, prognostic and therapeutic implications. In daily clinical practice, the use of ultrasound in the assessment of joint and tendon involvement in patients with systemic lupus erythematosus is still limited. Several methodological issues encountered in ultrasound studies evaluating musculoskeletal involvement in systemic lupus erythematosus patients need to be addressed in order to improve both the reliability and clinical usefulness of ultrasound findings. This paper reviews ultrasound studies assessing musculoskeletal involvement in patients with systemic lupus erythematosus, highlighting certainty, limits, potential applications and future perspectives of ultrasound use in systemic lupus erythematosus patients.

Systemic lupus erythematosus arthropathy: the sonographic perspective.

Background Despite being promising, the use of ultrasound (US) in the assessment of musculoskeletal manifestations of systemic lupus erythematosus (SLE) is still limited. Literature on this topic is scarce and the spectrum and clinical relevance of US abnormalities has not yet been outlined. With this paper, we aim to explore the panel of joint and tendon US findings in a group of SLE patients. Methods Twenty-five consecutive SLE patients, with current or medical history of musculoskeletal symptoms, were studied. All patients underwent routine clinical examination and US evaluation. The US examination targeted sites clinically involved in the physical examination and/or indicated as painful in the patient's medical history. Results One or more US changes were found in all the patients. US abnormalities were detected in 85 out of the 243 scanned joints (35%), in 70 out of the 215 scanned tendons (32.6%) and in 10 out of the 41 scanned entheses (24.4%). Synovial effusion, synovial hypertrophy, "mixed" synovitis (coexistence of synovial effusion and synovial hypertrophy), joint dislocation, bone erosion, and cartilage damage were found in 9.5%, 11.5%, 14%, 3.7%, 2.1%, and 4.5% of the scanned joints, respectively. Tenosynovitis, tendon dislocation, tendon tear, tendon thinning, and tendinitis/peritendinitis were detected in 17.7%, 8.4%, 0.9%, 4.2%, and 4.7% of the scanned tendons, respectively. Power Doppler signal, hypoechogenicity, thickening, enthesophytes, calcifications, and bone erosions were detected at the entheseal level in 12.2%, 9.8%, 12.2%, 7.3%, 7.3%, and in 0% of the scanned entheses, respectively. Conclusions This study revealed an unexpectedly wide heterogeneity of US pathologic findings in the joints and tendons of patients with SLE. A broad spectrum of US changes also involving anatomic structures not considered in previous investigations, including entheses and tendons with no synovial sheath, was detected. These preliminary results suggest that US is able to identify several US "patterns" whose clinical, prognostic, and pathogenetic significance is still to be defined.

Prenatal prediction of postnatal large-for-dates neonates using a simplified MRI method: comparison with conventional 2D ultrasound estimates.

OBJECTIVE: To evaluate the performance of a simple semi-automated method for estimation of fetal weight (EFW) using magnetic resonance imaging (MRI) as compared with two-dimensional (2D) ultrasound (US) for the prediction of large-for-dates neonates. METHODS: Data of two groups of women with singleton pregnancy between March 2011 and May 2016 were retrieved from our database and evaluated retrospectively: the first group included women who underwent US-EFW and MRI-EFW within 48 h before delivery and the second group included women who had these evaluations between 35 + 0 weeks and 37 + 6 weeks of gestation, more than 48 h before delivery. US-EFW was based on Hadlock et al. and MRI-EFW on the formula described by Baker et al. For MRI-EFW, planimetric measurement of the fetal body volume (FBV) was performed using a semi-automated method and the time required for measurement was noted. Outcome measure was the performance of MRI-EFW vs US-EFW in the prediction of large-for-dates neonates, both ≤ 48 h and > 48 h before delivery. Receiver-operating characteristics (ROC) curves for each method were compared using the DeLong method. RESULTS: Of the 270 women included in the first group, 48 (17.8%) newborns had birth weight ≥ 90th centile and 30 (11.1%) ≥ 95th centile. The second group included 83 women, and nine (10.8%) newborns had birth weight ≥ 95th centile. Median time needed for FBV planimetric measurements in all 353 fetuses was 3.5 (range, 1.5-5.5) min. The area under the ROC curve (AUC) for prediction of large-for-dates neonates by prenatal MRI performed within 48 h before delivery was significantly higher than that by US (for birth weight ≥ 90th centile, difference between AUCs = 0.085, standard error (SE) = 0.020, P < 0.001; for birth weight ≥ 95th centile, difference between AUCs = 0.036, SE = 0.014, P = 0.01). Similarly, MRI-EFW was better than US-EFW in predicting birth weight ≥ 95th centile when both examinations were performed > 48 h prior to delivery (difference between AUCs = 0.077, SE = 0.039, P = 0.045). CONCLUSION: MRI planimetry using our purpose-designed semi-automated method is not time-consuming. The predictive performance of MRI-EFW performed immediately prior to or remote from delivery is significantly better than that of US-EFW for the prediction of large-for-dates neonates.

Long-term survival, prevalence, and cure of cancer: a population-based estimation for 818 902 Italian patients and 26 cancer types.

BACKGROUND: Persons living after a cancer diagnosis represent 4% of the whole population in high-income countries. The aim of the study was to provide estimates of indicators of long-term survival and cure for 26 cancer types, presently lacking. PATIENTS AND METHODS: Data on 818 902 Italian cancer patients diagnosed at age 15-74 years in 1985-2005 were included. Proportions of patients with the same death rates of the general population (cure fractions) and those of prevalent patients who were not at risk of dying as a result of cancer (cure prevalence) were calculated, using validated mixture cure models, by cancer type, sex, and age group. We also estimated complete prevalence, conditional relative survival (CRS), time to reach 5- and 10-year CRS >95%, and proportion of patients living longer than those thresholds. RESULTS: The cure fractions ranged from >90% for patients aged <45 years with thyroid and testis cancers to <10% for liver and pancreatic cancers of all ages. Five- or 10-year CRS >95% were both reached in <10 years by patients with cancers of the stomach, colon-rectum, pancreas, corpus and cervix uteri, brain, and Hodgkin lymphoma. For breast cancer patients, 5- and 10-year CRSs reached >95% after 19 and 25 years, respectively, and in 15 and 18 years for prostate cancer patients. Five-year CRS remained <95% for >25 years after cancer diagnosis in patients with liver and larynx cancers, non-Hodgkin lymphoma, myeloma, and leukaemia. Overall, the cure prevalence was 67% for men and 77% for women. Therefore, 21% of male and 31% of female patients had already reached 5-year CRS >95%, whereas 18% and 25% had reached 10-year CRS >95%. CONCLUSIONS: A quarter of Italian cancer patients can be considered cured. This observation has a high potential impact on health planning, clinical practice, and patients' perspective.

Novelties in slipped capital femoral epiphysis imaging: A narrative review.

Rationale and objectives: Imaging plays a key role in Slipped Capital Femoral Epiphysis diagnosis and severity assessment. In the last two decades, signs and measurements emerged in literature showed potential to help in SCFE diagnosis and tailoring treatment. The purpose of this review is to collect and discuss new imaging signs, measurements, and techniques according to investigations published after 2000 to improve SCFE diagnosis. Material and methods: The PubMed, Scopus, and Science Direct databases were used to search for relevant articles related to imaging in SCFE diagnosis from January 2000 to March 2023. Article selection and review was performed by two board-certified radiologists). Article quality assessment were conducted by authors using QUADAS-2 and SANRA evaluation tools. Results: The research resulted in a total of 2577 articles. After duplicates removal and abstract analysis, 28 articles were finally selected for full-text analysis. Seventeen articles were focused on Radiographs, 6 on CT, 1 on both Radiographs and CT, 4 on MRI. No study focused on ultrasound was selected. Conclusions: Use of modified Klein's line and S-sign may improve radiographs accuracy in daily routine. Lucency sign may help in early diagnosis on radiographs. Preoperative CT may be useful in planning a tailored treatment predicting SCFE severity and instability. MRI is the most accurate modality to diagnose SCFE at early stage. Nevertheless, it cannot be used to predict the risk of contralateral SCFE. Risk prediction can be assessed with radiographs, using a new rapid mOBS. Further investigation and validation of these sign is needed.

Cancer prevalence in United States, Nordic Countries, Italy, Australia, and France: an analysis of geographic variability.

BACKGROUND: The objectives of this study were to quantitatively assess the geographic heterogeneity of cancer prevalence in selected Western Countries and to explore the associations between its determinants. METHODS: For 20 cancer sites, 5-year cancer prevalence, incidence, and survival were observed and age standardised for the mid 2000s in the United States, Nordic European Countries, Italy, Australia, and France. RESULTS: In Italy, 5-year crude prevalence for all cancers was 1.9% in men and 1.7% in women, while it was ∼1.5% in all other countries and sexes. After adjustment for the different age distribution of the populations, cancer prevalence in the United States was higher (20% in men and 10% in women) than elsewhere. For all cancers combined, the geographic heterogeneities were limited, though relevant for specific cancers (e.g., prostate, showing >30% higher prevalence in the United States, or lung, showing >50% higher prevalence in USA women than in other countries). For all countries, the correlations between differences of prevalence and differences of incidence were >0.9, while prevalence and survival were less consistently correlated. CONCLUSION: Geographic differences and magnitude of crude cancer prevalence were more strongly associated with incidence rates, influenced by population ageing, than with survival rates. These estimates will be helpful in allocating appropriate resources.

Measurement of the plasma astrophysical S factor for the 3He(d,p)4He reaction in exploding molecular clusters.

The plasma astrophysical S factor for the 3He(d,p)4He fusion reaction was measured for the first time at temperatures of few keV, using the interaction of intense ultrafast laser pulses with molecular deuterium clusters mixed with 3He atoms. Different proportions of D2 and 3He or CD4 and 3He were mixed in the gas target in order to allow the measurement of the cross section for the 3He(d,p)4He reaction. The yield of 14.7 MeV protons from the 3He(d,p)4He reaction was measured in order to extract the astrophysical S factor at low energies. Our result is in agreement with other S factor parametrizations found in the literature.

Temperature measurements of fusion plasmas produced by Petawatt-Laser-Irradiated D2 - (3)He or CD4 - (3)He clustering gases.

Two different methods have been employed to determine the plasma temperature in a laser-cluster fusion experiment on the Texas Petawatt laser. In the first, the temperature was derived from time-of-flight data of deuterium ions ejected from exploding D(2) or CD(4) clusters. In the second, the temperature was measured from the ratio of the rates of two different nuclear fusion reactions occurring in the plasma at the same time: D(d,(3)He)n and (3)He(d,p)(4)He. The temperatures determined by these two methods agree well, which indicates that (i) the ion energy distribution is not significantly distorted when ions travel in the disassembling plasma; (ii) the kinetic energy of deuterium ions, especially the "hottest part" responsible for nuclear fusion, is well described by a near-Maxwellian distribution.

Predictive role of capillaroscopic skin ulcer risk index in systemic sclerosis: a multicentre validation study.

UNLABELLED: Introduction The early detection of systemic sclerosis (SSc) patients at high risk of developing digital ulcers could allow preventive treatment, with a reduction of morbidity and social costs. In 2009, a quantitative score, the capillaroscopic skin ulcer risk index (CSURI), calculated according to the formula 'D×M/N(2'), was proposed, which was highly predictive of the appearance of scleroderma digital ulcers within 3 months of capillaroscopic evaluation. OBJECTIVES: This multicentre study aims to validate the predictive value and reproducibility of CSURI in a large population of SSc patients. METHODS: CSURI was analysed in 229 unselected SSc patients by nailfold videocapillaroscopy (NVC). All patients were re-evaluated 3 months later with regard to the persistence and/or appearance of new digital ulcers. RESULTS: 57 of 229 patients presented with digital ulcers after 3 months. The receiver operating characteristic curve analysis showed an area under the curve of 0.884 (95% CI 0.835 to 0.922), with specificity and sensitivity of 81.4% (95% CI 74.8 to 86.89) and 92.98% (95% CI 83.0 to 98.0), respectively, at the cut-off value of 2.96. The reproducibility of CSURI was validated on a random sample of 81 patients, with a κ-statistic measure of interrater agreement of 0.8514. CONCLUSIONS: The role of CSURI was confirmed in detecting scleroderma patients with a significantly high risk of developing digital ulcers within the first 3 months from NVC evaluation. CSURI is the only method validated to predict the appearance of digital ulcers and its introduction into routine clinical practice might help optimise the therapeutic strategy of these harmful SSc complications.

Clinical features of gout.

Gout is a metabolic disease characterized by hyperuricemia and the deposition of monosodium urate (MSU) crystals in the joints and soft tissues, consisting of a self-limited acute phase characterized by recurrent attacks of synovitis and a chronic phase in which inflammatory and structural changes of the joints and periarticular tissues may lead to persistent symptoms. Acute gout is characterized by a sudden monoarthritis of rapid onset, with intense pain, mostly affecting the big toe (50% of initial attacks), the foot, ankle, midtarsal, knee, wrist, finger, and elbow. Acute flares also occur in periarticular structures, including bursae and tendons. The presence of characteristic MSU crystals in the joint fluid, appearing needle-like and showing strong negative birefringence by polarized microscopy, is pivotal to confirm the diagnosis of gout. The time interval separating the first attack from subsequent episodes of acute synovitis may be widely variable, ranging from a few days to several years. During the period between acute attacks the patient is asymptomatic even if MSU deposition may continue to increase silently. The factors that control the rate, location, and degree of ongoing deposition in gouty patients are not well defined. Chronic gout is the natural evolution of untreated hyperuricemia in patients with gouty attacks followed by pain-free intercritical periods. It is characterized by the deposition of solid MSU crystal aggregates in a variety of tissues including joints, bursae and tendons. Tophi can occur in a variety of locations including the helix of the ear, olecranon bursa, and over the interphalangeal joints. Their development is usually related with both the degree and the duration of hyperuricemia. About 20% of patients with gout have urinary tract stones and can develop an interstitial urate nephropathy. There is a strong association between hyperuricaemia and the metabolic syndrome (the constellation of insulin resistance, hypertension, obesity and dyslipidaemia), and gouty patients often have a medical history of kidney disease, diabetes mellitus and signs of vascular illness such as coronary artery disease, heart failure and stroke, resulting with a poor overall quality of life.

Clinical, power Doppler sonography and histological assessment of the psoriatic plaque: short-term monitoring in patients treated with etanercept.

BACKGROUND: To date, the diagnosis of psoriasis is based on both clinical history and physical examination, and its severity is assessed by the Psoriasis Area and Severity Index (PASI). Continuous technological advances in the field of sonography have led to the development of equipment with high power Doppler frequency, which allows for very detailed morphological information regarding the dermal blood flow. OBJECTIVES: To compare power Doppler sonography (PDS) with clinical and histological findings before and after etanercept treatment in patients with psoriasis. METHODS: Twelve patients with a clinical diagnosis of psoriasis were enrolled in this study. The PASI, PDS and histological examinations were assessed in all patients on the same day at baseline, and after 12 weeks of biological treatment. PDS examination was performed by an experienced sonographer, using a sonographic system equipped with transducer ranging from 6 to 18 MHz and Doppler frequency ranging from 7 to 14 MHz. RESULTS: At follow up there was a significant decrease in PASI. A significant change was also detected for the PDS findings (P = 0·005). At baseline the median value for factor VIII staining was 1·5, and the median value for vascular endothelial growth factor (VEGF) staining was also 1·5. At follow up there was a significant decrease in both factor VIII and VEGF staining scores. Moreover, a positive correlation between reduction in PDS score and improvement in clinical and histological scores was found: Spearman's ρ = 0·639, P = 0·0022; Spearman's ρ = 0·619, P = 0·0013; Spearman's ρ = 0·765, P = 0·0002, respectively. CONCLUSIONS: Our results show a significant correlation between PDS findings and both PASI and histological degree of vascularization before and after etanercept treatment. These data provide evidence in favour of the validity of PDS in the assessment of dermal perfusional changes in patients with psoriatic plaques.

Accurate spectra for high energy ions by advanced time-of-flight diamond-detector schemes in experiments with high energy and intensity lasers.

Time-Of-Flight (TOF) methods are very effective to detect particles accelerated in laser-plasma interactions, but they show significant limitations when used in experiments with high energy and intensity lasers, where both high-energy ions and remarkable levels of ElectroMagnetic Pulses (EMPs) in the radiofrequency-microwave range are generated. Here we describe a novel advanced diagnostic method for the characterization of protons accelerated by intense matter interactions with high-energy and high-intensity ultra-short laser pulses up to the femtosecond and even future attosecond range. The method employs a stacked diamond detector structure and the TOF technique, featuring high sensitivity, high resolution, high radiation hardness and high signal-to-noise ratio in environments heavily affected by remarkable EMP fields. A detailed study on the use, the optimization and the properties of a single module of the stack is here described for an experiment where a fast diamond detector is employed in an highly EMP-polluted environment. Accurate calibrated spectra of accelerated protons are presented from an experiment with the femtosecond Flame laser (beyond 100 TW power and ~ 1019 W/cm2 intensity) interacting with thin foil targets. The results can be readily applied to the case of complex stack configurations and to more general experimental conditions.

European disparities in malignant digestive endocrine tumours survival.

The aim of this study was to report on malignant digestive endocrine tumours (MDET) prognosis in several European countries. We analysed survival data from 19 cancer registries in 12 European countries on 3,715 MDET diagnosed between 1985 and 1994. The overall 5-year survival rate was 47.5%. It was 58.1% for differentiated MDET and 8.1% for small-cell MDET (p < 0.001), 55.9% for patients under 65 and 37.0% for older patients. Survival rates for small intestinal and colorectal were higher than for the other sites. The 5-year relative survival rates were 60.3% in Northern Europe, 53.6% in Western Continental Europe, 42.5% in the UK, 37.6% in Eastern Europe (p < 0.001). Among well-differentiated pancreatic tumours, 5-year relative survival was 55.6% for insulinoma, 48.4% for gastrinoma, 33.4% for glucagonoma, 28.8% for carcinoid tumours and 49.9% for non-functioning tumours. The relative excess risk of death was significantly lower in Western Continental Europe and Northern Europe and significantly higher in Easter European compared to the UK. MDET differentiation, site, geographic area, age and sex, were independent prognostic factors. Overall, in Europe approximately half of the patients with MDET survive 5 years after the initial diagnosis. Prognosis varies with tumour differentiation, anatomic site and histological type. There are significant differences in survival from MDET among European countries, independently of other prognostic factors.

Cancer incidence and mortality in Spain: estimates and projections for the period 1981-2012.

BACKGROUND: National indicators of cancer burden are essential information for cancer surveillance and health planning, so that in countries with partial registration coverage and geographically variable risk patterns, such as Spain, this is even more relevant. This article provides estimates of cancer incidence in Spain for all cancers combined, with the single exception of non-melanoma skin cancer, and for major cancer sites over the period 1981-2006, with projections up to 2012. PATIENTS AND METHODS: Estimates were obtained by applying the MIAMOD method, a statistical back-calculation approach, to derive incidence from mortality and relative survival data. RESULTS: During the period 1981-2012, age-standardised incidence rates for all cancers rose from the beginning of the period and started to decline from 2000 onwards among men, and increased across the whole period among women. Differences in incidence trends between men and women might be attributable to the gender-specific case-mix of sites for all cancers, and to differences in risk factors specific to certain cancer sites in men and women, with smoking being the main factor accounting for these differences between the sexes. CONCLUSIONS: Estimates and projections of cancer incidence and mortality show divergent trends in Spain by sex and tumour type. This information is basic for planning and enhancing public health strategies and resources.

Quantitative and qualitative assessment of one rheumatology trainee's experience with a self-teaching programme in videocapillaroscopy.

OBJECTIVE: We have developed a self-taught course by which rheumatologists in training can learn how to conduct capillaroscopy examinations using a computerized videomicroscopy system. We assessed the effectiveness of this course by following the learning curve of one specialist trainee with no experience in capillaroscopy. METHODS: The student's training consisted of 10 practical sessions held on three consecutive days. The perceived difficulty in completing each session was graded from 0 (least difficult) to 10 (most difficult). All the images obtained were stored and the time spent by both the trainee and the tutor during the sessions was recorded. Each image was blindly judged by both the novice and the tutor for quality, assigning a score from 0 (lowest quality) to 10 (highest quality). The minimum acceptable score for standard clinical practice was considered to be >5. RESULTS: The student spent a total of approximately 5 non-consecutive hours engaged in 'direct' capillaroscopy and recorded a total of 172 images. The mean time required to produce each image varied from approximately 1.0 to 2.0 minutes. The perceived difficulty in completing a session decreased from the first to the last session. A quality score > 5 was assigned by the novice and tutor, respectively, to 16/49 images for the first group of sessions, 26/45 for the second group of sessions, and 56/78 for the third group of sessions. The overall agreement between the novice and tutor was good (K=0.617, SE=0.021). CONCLUSIONS: The monitoring of one rheumatologist in training indicates that novices can quickly learn, through an intensive self-teaching programme under the supervision of an expert, how to use computerized videomicroscopy to conduct capillaroscopy studies.

[The ultrasound assessment of the psoriatic arthritis: from joint to skin]. / L'ecografia nella valutazione della artrite psoriasica: dalla articolazione alla cute.

There is a growing number of papers investigating the diagnostic potential of ultrasonography in the assessment of patients with psoriatic arthritis and supporting its higher sensitivity over clinical examination in the diagnosis of synovitis, enthesitis and tenosynovitis. Less attention has been paid on both skin and nail, frequently involved in this condition. The aim of this paper is to show the potential of ultrasound in a multi-target assessment (joints, tendons, entesis, skin and nails) in patients with psoriatic arthritis, using the last generation ultrasound equipment.
